  • the dialkyl dicarbonates such as in particular dimethyl dicarbonate or diethyl dicarbonate, are a special cold disinfectant and have a number of advantages.
  • the outstanding advantage lies in the fact that taste and color are not affected, in contrast to hot filling.
  • persistent preservatives such as sodium benzoate or benzoic acid or potassium sorbate or sorbic acid, the advantage consists in particular in the absence of any impairment of taste and the disappearance of the effect. Due to the decomposition of the dialkyl dicarbonates into harmless components, no preservative or preservative is consumed by the actual consumer.
  • the devices with diaphragm pumps usually consist of a magnetically or electrically driven diaphragm pump, storage vessels, a device attached to the beverage line for atomizing the dialkyl dicarbonate, the flow meter attached to the beverage line, and an electronic control system. Dosing pumps of this type are usually permanently installed in the beverage line.
  • the dosing pumps should be suitable for several different performance parameters, especially for small and very small quantities. In addition, these dosing pumps should have a high level of accuracy when dosing, a high atomization pressure and a wide control range.
  • Dialkyl dicarbonates are thus dosed proportionally into the beverage tube in the required amount.
  • Examples of these pumps are the VelcorinDT devices from Lanxess.
  • WO1998042983A1 discloses a metering pump for the metered delivery of liquids.
  • the dosing pumps used for such devices and methods must meet different performance parameters. On the one hand, they should be suitable for supplying small or very small quantities.
